Ukusetyenziswa
I-anhydride ye-butyric isetyenziswa kakhulu njenge-acylating reagent kwi-organic synthesis. Ingasabela kunye nee-alcohols, ii-phenols, ii-amines, njl.njl. ukwenza ii-esters ezifanelekileyo, ii-phenyl ethers, ii-amides kunye nezinye iikhompawundi. I-anhydride ye-butyric ingasetyenziswa njengezinto eziluhlaza zokugquma, iidayi kunye neeplastiki. I-anhydride ye-butyric ingalungiswa ngokuphendula i-butyric acid kunye ne-acetic anhydride. Iimeko zokusabela zihlala zenziwa phantsi kweemeko ze-asidi kunye namaqondo obushushu aphantsi. I-anhydride ye-butyric iyacaphukisa kwaye iyakonakalisa kwaye inokubangela ukukruquka emehlweni, kulusu, kwindlela yokuphefumla kunye nenkqubo yokugaya ukutya. Ngexesha lokusebenza, kufuneka kuthathwe ingqalelo ukuze kuthintelwe ukudibana nolusu kunye namehlo, kwaye kuqinisekiswe ukuba utyando lwenziwa phantsi kweemeko zomoya opholileyo.
Lulwelo olungenambala nolucacileyo olunevumba elibi. Ubuninzi balo buyi-0.9668 (20/20℃), iqondo lokunyibilika liyi--75℃, kwaye iqondo lokubila liyi-198℃. Lunyibilika kwizinyibilikisi zendalo ezifana ne-ether. Lubola lube yi-butyric acid xa ludibana namanzi. Lusabela kwii-alcohols ukuze lwenze ii-esters. Lulwelo olungenambala, olucacileyo nolunokutsha. Lunyibilika emanzini kwaye lubola ukuze lwenze i-butyric acid, kwaye lunyibilika kwi-ether.
Ukupakishwa kunye nokuthunyelwa
195 kg/idrama okanye ngokweemfuno zomthengi.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
